Which protocol allows a host to obtain its network configuration automatically?

• A. Dynamic Host Configuration Protocol
• B. Simple Network Management Protocol
• C. File Transfer Protocol
• D. Hypertext Transfer Protocol

Answer: (A)

Automatic network configuration is provided by a protocol that lets a host obtain its IP address and other network settings from a server. This protocol, DHCP, simplifies connectivity by dynamically assigning IP addresses, subnet masks, gateways, and DNS information to clients. The process typically involves the host broadcasting a request, a DHCP server offering a configuration, and the host acknowledging to finalize the lease. This avoids manual setup and prevents IP conflicts by centralizing assignment within a defined pool, while also allowing settings like DNS servers and lease durations to be distributed automatically.

SNMP is for managing and monitoring devices on a network. FTP is for transferring files between hosts. HTTP is the protocol used to access web resources.
